One Who Walks by the River May End Up With Wet Feet in Chinese / Japanese...

常在河邊走哪能不濕鞋 is an old Chinese proverb that is sometimes compared to the English saying “Shit Happens.”

It's a reflection that there are risks in life, and you should not be surprised when things don't go your way.

A secondary translation might be, “When walking by a river, often one cannot avoid wet shoes.”
